Which scenario increases the likelihood of lahar formation following pyroclastic flow events?

💡 Explanation

Lahars are mudflows composed of volcanic ash and debris; excessive rainfall on readily erodible ash accelerates **slope failure**, because the addition of water lubricates ash particles, therefore increasing lahar likelihood, rather than drier or stable configurations.
